Ive stayed in a variety of hotels across china over the past decade and Win Win would have to be the most value for money in terms of room size.
Thier standard deluxe room ($95Usd) was akin to a suite at most other hotels. Spacious living with table and couch area, massive bathroom and ample bed.
The only negative is its proximity from the city, though having changed to the Nanning Marriott after my initial stay i would make a compromise on this seeing as i was paying x3 for 1/3 of the room size.
Staff were great, breakfast was ample and i would make this my first stop when returning to nanning. If only there was a McDonalds close i would probably take up permanent residence!!! haha.
